Bill Gates, along with Facebook founder Mark Zuckerberg and his Amazon counterpart Jeff Bezos, have been named among the planet’s eight men, who combined are worth as much as the poorest 50% of the world.

According to a report published on Monday (16 January) by anti-poverty charity Oxfam, the eight, which also include Amancio Ortega — the founder of the Spanish fashion chain Zara — and Berkshire Hathaway chief executive Warren Buffett, are as wealthy as the 3.6 billion people who make up the poorest half of the globe’s population.

Bill Gates

The founder of Microsoft has been a mainstay in the world’s richest men list, claiming the top spot in 17 of the 22 years he has made the grade, and he has been the world’s wealthiest man since 2014.

Gates, whose net wealth is currently estimated to be at $84.2bn, is renowned for regularly selling his shares in Microsoft, and as of September 2016 he only owned a 2.5% stake in the computer giant. However, while Gates is rightly identified with the company he founded, Microsoft amounts for only 13% of his fortune, as the Seattle-born billionaire has investments in a host of other ventures.

The 61-year-old, who has held the title of America’s richest person for 23 years running, has donated to charity throughout his career and he and his wife Melinda plan to devolve around 95% of their wealth to philanthropic causes.

The Spaniard, whose net worth stands at $72.4bn, still owns almost 60% of the Inditex company, which owns Zara as well as a number of other brands including Massimo Dutti, Oysho, Pull and Bear and Bershka, among others.

Ortega made light work of Spain’s financial crisis as he gained $45bn between 2009 and 2014.
